Practice patterns of cardiovascular magnetic resonance use in the diagnosis of pediatric myocarditis: A survey-based study.

Background: Cardiovascular magnetic resonance (CMR) is used to diagnose myocarditis in adults and children based on the original Lake Louise criteria (LLC) and more recently the revised LLC. The major change included in the revised LLC was the incorporation of parametric mapping, which significantly increases the sensitivity and specificity of diagnosis. Subsequently, scientific statements have recommended the use of parametric mapping in the diagnosis of myocarditis in children.

Mind the Gap! Working Toward Gender Equity in Pediatric and Congenital Heart Disease: Present and Future.

Evidence from medicine and other fields has shown that gender diversity results in better decision making and outcomes. The incoming workforce of congenital heart specialists (especially in pediatric cardiology) appears to be more gender balanced, but past studies have shown many inequities. Gender-associated differences in leadership positions, opportunities presented for academic advancement, and recognition for academic contributions to the field persist.

Coarctation Duration and Severity Predict Risk of Hypertension Precursors in a Preclinical Model and Hypertensive Status Among Patients.

Background: Coarctation of the aorta (CoA) often leads to hypertension posttreatment. Evidence is lacking for the current >20 mm Hg peak-to-peak blood pressure (BP) gradient (BPGpp) guideline, which can cause aortic thickening, stiffening, and dysfunction. This study sought to find the BPGpp severity and duration that avoid persistent dysfunction in a preclinical model and test if predictors translate to hypertension status in patients with CoA.

Coarctation duration and severity predict risk of hypertension precursors in a preclinical model and hypertensive status among patients.

Background: Coarctation of the aorta (CoA) often leads to hypertension (HTN) post-treatment. Evidence is lacking for the current >20 mmHg peak-to-peak blood pressure gradient (BPGpp) guideline, which can cause aortic thickening, stiffening and dysfunction. This study sought to find the BPGpp severity and duration that avoid persistent dysfunction in a preclinical model, and test if predictors translate to HTN status in CoA patients.

Palliation Plus Ventricular Assist Device Insertion in 15 Neonates and Infants With Functionally Univentricular Circulation.

Background: We report 15 high-risk neonates and infants with functionally univentricular circulation stabilized with initial surgical palliation plus ventricular assist device (VAD) insertion (PALLIATION+VAD) in preparation for transplantation.

Methods: Fifteen functionally univentricular patients with ductal-dependent systemic circulation (8 hypoplastic left heart syndrome, 1 hypoplastic left heart syndrome-related malformation: 7 neonates, 2 infants) or ductal-dependent pulmonary circulation (6 hypoplastic right heart syndrome: 5 neonates, 1 infant) presented with anatomical and/or physiological features associated with increased risk for conventional univentricular palliation (large coronary sinusoids with ventricular-dependent coronary circulation, severe systemic atrioventricular valvar regurgitation, cardiogenic shock, or restrictive atrial septum). PALLIATION+VAD for patients with ductal-dependent systemic circulation was: VAD insertion plus application of bilateral pulmonary bands, stent placement in the arterial duct, and atrial septectomy, if needed.

Combined Hybrid Procedure and VAD Insertion in 9 High-Risk Neonates and Infants With HLHS.

Background: This report describes 9 high-risk neonates and infants with hypoplastic left heart syndrome (HLHS) who were stabilized with a combined hybrid approach and ventricular assist device (VAD) insertion (HYBRID+VAD) in preparation for heart transplantation.

Methods: A total of 9 patients with HLHS (7 neonates, 2 infants) presented with anatomic or physiologic features associated with an increased risk for conventional univentricular palliation with the Norwood operation (large coronary sinusoids or fistulas, severe tricuspid regurgitation, cardiogenic shock, restrictive atrial septum). These patients underwent combined VAD insertion (Berlin EXCOR, Berlin Heart, Inc, Berlin, Germany) and Stage 1 hybrid palliation (application of bilateral pulmonary bands, stent placement in the patent arterial duct, and atrial septectomy if needed).

Optimized Computed Tomography Angiography Protocol for the Evaluation of Thrombus in Patients with Fontan Anatomy.

The Fontan procedure is the final stage in the palliative surgical approach to patients with single-ventricle physiology. These patients have an increased risk for thromboembolic disease in the Fontan circuit, which can be evaluated by chest computed tomography angiography (CTA) in acute settings. However, false-positive results are common secondary to unusual streaming patterns in the Fontan circuit.

Impact of 3D Printouts in Optimizing Surgical Results for Complex Congenital Heart Disease.

Planning corrective and palliative surgery for patients who have complex congenital heart disease often relies on the assessment of cardiac anatomy using two-dimensional noninvasive cardiac imaging modalities (echocardiography, cardiac magnetic resonance imaging, and computed tomography scan). Advances in cardiac noninvasive imaging now include the use of three-dimensional (3D) reconstruction tools that produce 3D images and 3D printouts. There is scant evidence available in the literature as to what effect the availability of 3D printouts of complex congenital heart defects has on surgical outcomes.

Left Ventricular Aneurysm Following Blunt-Force Trauma in a Child.

• LV aneurysms are rare in the pediatric population. • Given different implications, it is key to distinguish aneurysm and pseudoaneurysm. • The authors describe multimodality imaging to manage a pediatric LV aneurysm.

Effect of prenatal diagnosis on hospital costs in complete transposition of the great arteries.

Objective: Prenatal diagnosis of congenital heart disease (CHD) is associated with improved clinical outcomes, yet its impact on the cost of hospitalization is not well described. We hypothesized that prenatal diagnosis of complete transposition of the great arteries (d-TGA) results in lower total hospital costs compared with postnatal diagnosis.

Methods: Retrospective analysis of infants with d-TGA repaired at our center from July 2006 to 2014.

Maternal hyperoxygenation: A potential therapy for congenital heart disease in the fetuses? A systematic review of the current literature.

Objectives: To assess efficacy, safety, outcomes, and intrauterine complications following maternal hyperoxygenation (MH) therapy in fetuses with congenital heart disease (CHD).

Methods: A systematic review was performed following an electronic search of databases. Articles were published before January 1, 2017, in an English-language and non-English-language journals (with English translations), and included human fetuses and expectant mothers with a fetal diagnosis of CHD who received MH.

Cardiovascular Magnetic Resonance Findings Late After the Arterial Switch Operation.

Background: Despite its robust diagnostic capabilities in adolescents and adult patients after the arterial switch operation, little information is available on the cardiovascular magnetic resonance findings in this population.

Methods And Results: The cardiovascular magnetic resonance findings of 220 consecutive patients evaluated in our center were retrospectively reviewed (median age at cardiovascular magnetic resonance, 15.4 years; 66.

Goldenhar Syndrome Associated with Extensive Arterial Malformations.

Goldenhar Syndrome is characterized by craniofacial, ocular and vertebral defects secondary to abnormal development of the 1st and 2nd branchial arches and vertebrae. Other findings include cardiac and vascular abnormalities. Though these associations are known, the specific anomalies are not well defined.

Left Ventricular Metastasis in Neuroblastoma: A Case Report.

Neuroblastoma is the most common extracranial solid tumor in children. Most common sites of metastases from neuroblastoma are bone marrow, bone and lymph nodes, however cardiac metastasis is rarely seen. Metastatic cardiac tumors are 20 to 40 times more common than primary cardiac tumors.

Cardiovascular magnetic resonance imaging-based computational fluid dynamics/fluid-structure interaction pilot study to detect early vascular changes in pediatric patients with type 1 diabetes.

We hypothesized that pediatric patients with type 1 diabetes have cardiac magnetic resonance (CMR) detectable differences in thoracic aortic wall properties and hemodynamics leading to significant local differences in indices of wall shear stress, when compared with age-matched control subjects without diabetes. Pediatric patients with type 1 diabetes were recruited from Children's Hospital of Wisconsin and compared with controls. All underwent morning CMR scanning, 4-limb blood pressure, brachial artery reactivity testing, and venipuncture.

Ventricular septal defect.

Background: Ventricular septal defects are the commonest congenital cardiac malformations. They can exist in isolation, but are also found as integral components of other cardiac anomalies, such as tetralogy of Fallot, double outlet right ventricle, or common arterial trunk. As yet, there is no agreement on how best to classify such defects, nor even on the curved surface that is taken to represent the defect.

Pocket echocardiography system for detection of patent ductus arteriosus in neonates.

Background: Neonates are commonly referred for a cardiology consult and an echocardiogram to rule out patent ductus arteriosus (PDA).

Objectives: Evaluate the usefulness of current pocket echocardiography system (PES) in PDA detection compared to traditional full-featured echo system (FFES).

Hypothesis: The determination of the presence of a PDA in neonates can be done using PES.

Long-term outcomes of the neoaorta after arterial switch operation for transposition of the great arteries.

Background: After the arterial switch operation (ASO) for transposition of the great arteries (TGA), the native pulmonary root and valve function in the systemic position, and the long-term risk for neoaortic root dilation and valve regurgitation is currently undefined. The aim of this study was to determine the prevalence and progression of neoaortic root dilation and neoaortic valve regurgitation in patients with TGA repaired with the ASO.

Methods: Measurements of the neoaortic annulus, neoaortic root at the level of the sinuses of Valsalva, and the degree of neoaortic regurgitation were assessed by serial transthoracic echocardiograms on 124 patients with TGA at a median follow-up of 7.
